MACHINE FOR MAKING SAND OR CHEMICAL BRICK.

SPECIFICATION forming part of Letters Patent No. 74 ,574, dated October27, 1903. Application filed July a1, 1903. Serial No. 167,744. (Nomodel.)

To all whom it may concern:

Be it. known that 1, CHARLES W. BOYLE, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented new and usefulImprovements in Machines for Making Sand orChemical Brick, of which the following is a specification.

This invention relates to certain new and to useful improvements inmachines for making sand or chemical brick and analogous purposes.

The objects of the invention are, first, to provide suitable means forraising the molds from over the brick in such a manner that the brickmay be removed from the machine without interference with the molds;second, to provide a machine of the class described that will mold brickto sharp square corners without breaking the same; third, to provide ameans whereby the eccentric that actuates the press-block will, with thebow, be connected directly with the press-block, thereby enabling me todispense with a connecting- 2 5 rod; fourth, to provide a brick-machinethat may be readily and quickly adjusted to the work of pressing brickor tile of different sizes, thicknesses, forms, or configurations;fifth, to provide a brick-machine having a 0 reliable uniform feed forthe material to the molds; sixth, to provide suitable mechanism wherebythe bricks or other objects formed in the molds can be readily andquickly removed without breakage. These objects I v3, 5 accomplish bymeans of the mechanism illustrated in the accompanying drawings, inwhich-= Figure 1 is an elevation of a machine constructed in accordancewith my invention,

0 showing the relative position of the several parts which operate toproduce the brick.

Fig. 2 shows a sectional elevation of the same on the line w w of Fig.3. Fig. 3 is a sectional elevation on the line y y of Fig. 2, Fig. 4 isa sectional plan of the same on the line 2 z of Fig. 1. Fig. 5 is asectional view of the mold and the feed-box and the ways upon which themolds and mold-board are operated on the line 0: 0c of Fig. 4. Fig. 6 isa sectional View of the driving-wheel mechanism,

showing the projecting point for moving the .end of the bow,

friction-wheel at the proper time. Fig. 7 is a vertical sectional viewof the feed-box and brick-molds, on an enlarged scale, showing therelation of the feed-box to the mold.

Similar letters refer to similar parts through out the several views.

A represents the supporting-frame of the machine.

A is the bed that supports the mold and mold-board for pressing thebrick.

B is the press-block, which is supported in its ways or slides B so asto reciprocate vertically, and this press-block is actuated by means ofthe eccentric D, which is mounted upon the shaft E, and the eccentricbow or head 0, which is connected directly with the press-block B bymeans of the lugs c and f, so that the head slides laterally across theblock concurrent with its vertical reciprocations, thus preventing thenecessity of a connecting-rod between the eccentric bow and thepress-block. Inasmuch as the weight of the press-block is not great andits upward motion may be assisted by the lever N and the knuckle-jointL, I do not deem it neces sary to place any antifriction-rollers betweenthe bearings c and f; but the downward pressure on the press-block beingseveral tons it is necessary to provide suitable means to reduce thefriction to a minimum, and for this purpose I place a series of smallrollers S in position to receive and evenly distribute the pressure andto allow the head or bow to move laterally with the least possiblefriction. As it is necessary to have a smooth hard surface for therollers to travel upon, I provide a detachable plate F, preferablyfitted with side guards to prevent the rollers from sliding out endwiseand with the bearingsf at the upper ends of the side guardsto engagewith the bearings c on the eccentric bow. To prevent the rollers fromrolling out of the bearings, I provide stops f at each tween them toallow the rollers room to work leaving sufficient space be-- freely andwithoutinterfering with each other q or with the stops.

The eccentric D is caused to revolve with the shaft E, which may be madeto revolve by a lever T, or the lever may be removed,

as shown in Fig. l, and the eccentric be driven 1 forms, shapes, depths,

by power by the action of the friction-wheel Q upon the periphery of thewheel E, as shown in Fig. The friction-wheel Q is driven by the shaft Qby any ordinary device for transmitting power, as by a belt over thepulley Q, and is drawn against the periphery of the wheel E by means ofthe lever R through the medium of the rod R acting upon the sliding boxor bearing R and is pressed away from the wheel at the proper time bythe projecting knob e on the wheel E. This projection is located on thewheel E, so that it will throw the friction-wheel off just after theeccentric has passed the lowest point and started upon its upward motionsufliciently to slightly relieve the pressure upon the brick, where itshould stand a moment to give the brick an opportunity to assume itsproper form and shape and become sufiicien'tly set to retain its form,when the press-block may be raised by properly manipulating the lever R,as hereinbefore described.

The lower portion 12 of the press-block is preferably made detachable,so that various and patterns of mold may be applied as it is desired tovary the form, size, thickness, or configuration of the tile or brick tobe manufactured.

The molds may be made of any desired form, and the portion 1) of thepress-block must be made to exactly fit them, as indicated in Figs. 2and 3, and they are filled by passing them out under the feed-box 0,(see Fig. 1,) which is kept properly filled with the proper materialfrom which the brick or tile are to be made by passing it in properquantities through the tube P.

The mold G is supported by placing the projecting fiange 9 into thegroove 2' in the ways or tracks I, which latter are supported by meansof the bolts J, the lower ends of which are secured in the yoke K, towhich the knuckle-joint or compound lever L is attached and so arrangedthat the turning of the lever M with the lever N will raise and lowerthe mold, as desired.

In order to operate the lever-joint L M by machinery, I connectthe leverN to the pulley 4 by means of the connecting pivoted arm 9. The pivotedarm 9 is provided with a pivot 11, which passes through at the slot 12in the spoke or extension of the pulley 4.

5 is a friction-pulley on the hub of the pulley 4. This pulley 4 engageswith the friction-wheel E to operate the lever N and is operated bymeans of the belt 10, which passes over the pulley on the shaft Q.

The lever 2 is pivoted to the frame and is connected, by means ofaconnecting-rod 6, to the journal-box of the pulley 4, which journal-boxhas a laterally-sliding motion, and by operating the lever 2 the belt 10may slack'ed, so as not to operate the operatingpulley 4, and bytightening the belt 10 by means of said lever the operating-pulley 4 isset in motion, operating the lever N and the joint L M for the purposeof raising and lowering the mold.

To fill the mold, the same, together with the mold-board, is carried outon the track H under the feed box 0. In passing out the end of the moldengages the hook 17 and carries the sliding bottom 0, back with it sothat when the mold is in position, as indicated in dotted lines in Fig.5, it willbe filled with the filling material, and upon its return itwill draw the sliding bottom with it until the hook reaches the incline.At the end of the slot orguide 20, I provide a projection 19, whichcontacts with the incline of the hook. The hook 17 is pivoted at thepoint 18.

The mold and the mold-board are manipulated by means of the rack 72 andthe gearwheel W, as follows: The belt V passes around the shaft Q andthe pulley V on the shaft U and revolves this shaft upon the shaft Q,and this shaft in turn imparts motion to the shaft of U through themedium of the gearwheels U in the opposite direction from the shaft U.These shafts are provided at the opposite end with friction-pulleys u inposition to engage alternately with the pulley u on the shaft U. Thisshaft carries the gearwheel W, which meshes with the rack in. The end ofthe shaft U is actuated by means of the lever \V and the connecting-rodW, so that the friotion-pulley u may be made to engage one or the otherof the friction-pul-.

leys u on the shaft U or U to draw the mold and mold-board under thefeed-boX or to carry it back under the press-block or the mold-board andbrick to the tracks H, as indicated by the dotted lines in Figs. 1 and4.

The grooved tracks or supports I are continued under the box 0 bycorresponding tracks I, so that the mold is always supported by theflange g at its upper edge as well as upon the mold-board. Themold-board is held in position laterally by the guides h and is drawn bythe rack 71 by means of the upwardiy-projecting lugs h.

Having thus described my invention, what I claim to have invented, anddesire to secure by Letters Patent, is

1. The combination with a supportingframe, a press-block provided withinwardlyprojecting bearings, an eccentric, an eccentric bow or headprovided with ways corresponding to the bearings in the block, andantifrictional rollers between the bow and the block.
